Abstract: This article discloses an interaction method and apparatus, and electronic device and medium. The interaction method comprises: displaying an interaction interface after a user selects an interactive object via a selection interface and the interactive object receives an interaction invitation, wherein the interaction interface is configured to display pictures taken by the user and the interactive object in real time, the interaction interface comprises an interaction control for the user and the interactive object to interact while capturing in real time, the selection interface and the interaction interface are video capturing related interfaces, the video capturing related interfaces are related to capturing of an interactive video, and the interactive video is a video which is taken while the user and the interactive object interacts based on the interaction interface; obtaining a setting operation for the interaction control; and responding to the setting operation within the interaction interface.

Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.

Abstract: The present disclosure provides a display panel including a plurality of pixel units. Each of the pixel units includes a substrate; a first electrode layer; a light emitting layer; a second electrode layer; and a color shift compensation layer located between the first electrode layer and the second electrode layer and on a light emitting side of the light emitting layer. The color shift compensation layer is configured to compensate for a color shift of light emitted from the light emitting layer at different viewing angles. One of the first electrode layer and the second electrode layer includes a reflective electrode layer, and the other of the first electrode layer and the second electrode layer is a transflective electrode layer. A display device including such a display panel, and a method for manufacturing such a display panel are also provided.

Abstract: The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.

Abstract: A backlight source and a display device are provided. The backlight source includes a backplate (1), a light source (2) and a diffuser plate (3). The light source (2) is provided on a face of the backplate (1), the diffuser plate (3) is parallel to the face of the backplate (1), and the diffuser plate (3) is provided at a side of the backplate (1), where the light source (2) is provided, and is opposite to light source (2); and a support pole (31) is further provided between the diffuser plate (3) and the backplate (1), and the support pole (31) and the diffuser plate (1) are made of a same material and formed integrally.
